Gentlemen, I have a 1956 Mercury Montclair with a 312 engine and the merc o matic transmission. The tranny is leaking from the top. What could be leaking? Is there a breather up there that I can fix or plug up? Tried a stop leak it did nothing. It also leaks when car is not running. TY in advance

Are you sure  the trans is not overfilled?

Paul not only is it not overfilled it is almost empty of fluid. The dip stick has maybe an 1/8" of fluid on it.
